摘要:导电聚苯胺（PAN）是一种具有潜在应用价值的新型射频与微波吸收剂。在聚苯胺中添加各种导电填料如碳黑、石墨、金属粉或通过化学掺杂，可使电导率得到显著提高，而且比重小、易加工成型。本文简述其合成方法，用XRD、FTIR对其结构进行表征，初步测试了该材料对毫米波雷达的衰减效果，测试结果表明导电聚苯胺在8mm波波段具有衰减性。
Abstract:As the electrical conductivity of intrinsical polymer can be improved through chemical doping and adding the conducting powders (eg. carbon black, graphite and metal powder), moreover, PAN has little weight and can be processed easily, so it is the best promising material used as RF and microwave absorber. The synthetic craft of PAN is introduced in this paper, its structure is investigated with XRD, FTIR and its electrical conductivity is tested. The property of the conducting PAN shields the MMW radar is also discussed.
